trips. It should trip between 21 and 38 seconds.
IMPORTANT: Be sure to reinstall the thermis
tor after testing thermostat.
Thermal Fuse Test
A thermal fuse is used on this model. The thermal fuse is wired in series with the dryer gas
valve. If the thermal fuse opens, power is shut
off to the gas valve. (Centrifugal switch in motor also opens heater circuit.)
Once the thermal fuse has opened, it must be
replaced. Check for failed thermistor or other
cause of failure. Replace failed parts. See
Figure 1.
Thermistor Test or Dryer
Beeps 3 Times When Push To
Start (PTS) Pressed
An electronic temperature sensor called a
thermistor is used in this model in place of an
operating thermostat. The Even Heat Control
monitors the exhaust temperature using the
thermistor and cycles the heater relay on and
off to maintain the desired temperature.
Procedure
Begin with an empty dryer and a clean lint
screen.
1. Set the following configuration:
■

■
Door - must be closed
2. Press the Push To Start (PTS) switch.
a. If you hear three short beeps and the
dryer shuts off after several seconds, the
thermistor or wire harness is either
shorted or open. Check wire connec
tions at Even Heat Control and thermis
tor. If wiring is functional, replace the
thermistor: Unplug the dryer and remove
-
the front toe panel. Remove the two
wires and replace the thermistor as
shown in Figure 1.
b. If the dryer appears to operate correctly,
proceed to step 3.
3. Remove exhaust vent and start the dryer.
a. Turn Fabric Care/Temperature switch to
desired temperature to be tested, and
select 20 minutes on the Timed Dry dial.
Hold a glass bulb thermometer capable of
reading from 90°F to 180°F in the center of
the exhaust outlet. Measure exhaust tem
peratures with heater off and on. The
correct exhaust temperatures are as
follows:
